    Thanks, but I already read the FAQ.  If I don't get it wrong, these
sections state how to use generated source files (a task which I already
accomplished successfully).

    But how do I use a generated CMake include() file?  How do I tell CMake to
generate a file which can be read with include() in case it is not there
yet (or outdated)?  Is this possible at all?

Thanks,
